I am very skeptical. I have friends who have degrees in nuclear physics and this was my first choice for a career except when I saw the Fonda's in China Syndrome creating hysteria I decided to get into computer Science instead.
I know of no laws of physics that allow this gadget to work.
However this was also true when Einstein published his papers on special relativity. It took a generation of physicists to retire before that was proven. And as Richard Feynman said: There is plenty of room at the bottom as in we still have likely more to discover than we currently know.
Here is a reason the "customer" might not want to be known. Suppose it doesn't work. Politics says a major firm will walk away with egg on the face and no major firm wants this.
So we need to sit back and let these events unfold as they will. If it works then great. But it still does not solve a problem which has been solved in the 1960's through the 1990's This problem is the "spent fuel problem". There is enough energy sitting in the swimming pools on the current nuclear reactor sites to power our world for 1000's of years. Generation IV reactors like the molten salt reactor from Oak Ridge or the IFR which Argonne labs designed... either will burn that "spent fuel" and they can do this because the fuel is not "spent" at all. Its not waste. Its fuel.
These are tested designs and the physics is worked out and IMHO it is totally stupid to not be using them. It is totally fraudulent for the media and our governments to be totally misrepresenting the physics. Here is one example. I read in the papers that fuel reprocessing should not be allowed because:
The because is because of Plutonium. We can make bombs from Pu239. Well this is true. It is also true there is Pu239 in the "spent fuel". What is not told to the public is that there is also Pu240, Pu241 and Pu242 in that "spent fuel" and no one in their right mind would try to make a bomb with that stuff.
So what we should stop doing IMHO is enrichment because the main reason for this is to make bombs. Canada has the Candu and its proven and we don't need enrichment. We don't need to shut down NYSE:USU. I was a stock holder and made money. We need them to start doing reprocessing.
If we clean the crud from the "spent fuel" we can stuff it into Candu reactors and run them for 1000's of years. This is how we get rid of the nuclear "waste". At any time we can build the gen IV reactors.
But the thing is its still going to take a 1000's years to burn it and during this time there is going to be all the electricity our world needs flowing from these reactors.
If the e-Cat works then what? The nuclear industry dies and then who looks after the swimming pools.
In a way I hope the e-Cat doesn't work. I'd like to have one in my car and another heating my house but I think I would rather like to see a logical well thought out energy system which gets rid of the highly radioactive isotopes. This means fuel reprocessing and we shut down the enrichment industry because we already have too much.
